Abstract: FREE PISTON PUMP            ABSTRACT OF THE DISCLOSURE  In accordance with the present invention, a pumping unit (10) is disclosed.  The pumping unit includes shell structures (20, 22) each having a diaphragm (32, 38) therein to divide the pumping chamber within the structure into first and second compartments.  One-way valves permit material to travel from an inlet source to the first compartment and from the first compartment to an outlet source.  Deflection of diaphrams provides the impetus to draw material to the first compartment from the inlet source and drive the material to the outlet source.  The motion of the diaphrams is induced by a reciprocating piston assembly (94) within a cylinder (84). The motion acts through intermediate chambers (110, 112) filled with pumping fluid and acting on the opposite side of the diaphrams from the first compartments.  This permits isolation of the piston from the material being moved to prevent contamination.  Limit sensors (126, 128) may be provided to sense the limits of the piston assembly reciprocation for reversing motion of the piston assembly.

Abstract: ABSTRACT OF THE DISCLOSURE           A work support for use primarily with machine tools is provided by a double-acting, automatic, self-centering holding device including a set of three holding rollers which synchronously and equally move radially toward and away from a workpiece holding position to faci-litate the concentric positioning of workpieces of various diameter.  The simultaneous radial or centripetal displace-ment of the holding rollers is accomplished by means of a pair of double-acting symmetrical slots cut one in each of a pair of lever arms which in turn support one of the hold-ing rollers.  The synchronization of the symmetrical move-ments of the lever arms is obtained by the interaction of the slots on each lever arm with guide rollers commonly mounted on a cross arm mixed to an axially displaceable central control shaft.  The third holding roller is mounted on the end of the central control shaft directed toward the holding position of the workpiece.  The device is adapted to clamp a workpiece in a conventional fashion from the exterior of the workpiece and in addition to clamp a workpiece from the interior by means of forcing the rollers into engagement with the inner peripheral surface of an aperture in an end of the workpiece.

Abstract: ABSTRACT OF DISCLOSURE        A  method for detoxification of spent catalyst from a fluorination process includes the step of hydrolyzing such spent catalyst in the presence of aqueous calcium chloride to produce insoluble compounds which are separable from the acqueous medium. The spent catalyst is one which includes at least one antimony halide, such as SbCl5, SbF5, SbCl3 and/or SbF3, usually with some hologenated hydrocarbons, such as partially chlorinated methane, partially chlorinated ethane and/or chlorofluorocarbons of 1 to 5 carbon atoms, often in the presence of arsenic compounds, such as AsCl3, hydrofluoric acid, and antimony chlorofluoride, such as SbCl4F. The spent catalyst may be directly treated with the aqueous calcium chloride solution, very preferably with such solution containing small amounts of a transition metal ion, such as Fe++ or Fe+++, or aluminum ion, e.g., Al+++, after which volatile gases omitted are treated, an organic liquid phase is separated from an acqueous liquid phase containing dispersed precipitated insoluble compounds of antimony and arsenic (when arsenic is present), such as calcium salts of acids thereof, oxides, hydroxides and/or oxyhalides thereof resulting from the hydrolysis reaction, such insolubles are separated from the aqueous liquid medium, as by filtration, and the filtrate is neutralized with lime.  The neutralized filtrate, containing calcium chloride resulting from the neutralization reaction, may be returned to the hydrolysis step and/or may be further treated by a sulfide or hydrosulfide and a water soluble iron salt, such as aqueous solutions of sodium sulfide or sodium hydrosulfide, and ferric chloride, to co-precipitate compounds of antimony and arsenic, which may be removed from the aqueous medium, together with precipitated compounds of heavy metals which may be present, after which the filtrate may be discharged to a sewer after suitable monitoring to ensure that the contents of toxic materials are within permissable ranges for such discharge.  The antimony compounds removed during the process may be recovered and converted to useful form, as for reuse as fluorination catalysts, and other removed materials may also be recovered, regenerated and/or reused.

Abstract: ABSTRACT         Leaks or thin spots in containers, as well as mechanical faults, e.g. worn bearings, are detected by an ultrasonic energy indicator that includes a modulator that heterodynes ultrasonic signals received by a transducer and creates an audio signal related thereto.  The transducer includes a series arrangement of piezoelectric crystals feeding a field-effect transistor amplifier and the modulator operates in an amplitude modulation, suppressed-carrier mode which can be stabilized by a feedback loop.  For indicating the presence of the audio signal, either headphones or a meter or both are employed.  When leaks in a container are being detected, an ultrasonic generator is used which varies its output frequency slowly over a band of frequencies.  The leak detection technique can be improved by applying a thin layer of a liquid to the container surface so that pressure introduced into the container causes the formation and bursting of bubbles in the liquid that results in the production of ultrasonic energy.

Abstract: "METHOD FOR REMOVING HYDROGEN   SULFIDE FROM GAS STREAMS"                 Abstract For the simultaneous absorption and oxidation of hydrogen sulfide, gaseous mixtures are treated with an aqueous, alkaline scrubbing agent containing pentavalent vanadium as the oxidizing medium.  The hydrogen sulfide is absorbed by the scrubbing agent and oxidized to elemental sulfur with reduction of pentavalent vanadium to tetravalent vanadiu.  The thus-reduced scrubbing agent is then regenerated in the presence of a promoter by reoxidation of the tetravalent vanadium, and reused, the novelty of the process being the use of a source of an organic nitrogen compound, e.g., hexamethylenediamine, an inorganic amine, or a carbohydrate, e.g., sucrose, as the promoter.
